The race
There are spectators along much of the route. Race packs have been posted in the week before the race.
Cardiff
Cardiff is a compact capital where almost everything is within walking distance. The castle sits in the middle of the shopping streets, Principality Stadium is a few minutes away, and the Bay has restaurants and a boardwalk that suits a gentle shakeout.
Wales has its own language, and you will see Welsh on every sign: Caerdydd is the name of the city. Early October is mild and changeable, so carry a waterproof layer.
